To aZZwhom it may concern: 7

Be it known that I, MICHAEL B. RYAN, a citizen of the United States,residing at Boston, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Bed-Spring Fabrics, of which the following is a specification. The object of this invention is to provide a bed spring which shall be strong, light, cheap and durable. and which is so constructed that the parts are capable of being manufactured and assembled in an electric welding machine, so that when the spring is completed the different links composing the same are welded at their ends, forming a very strong and light construction, with completely closed eyes.

It is further the object of this invention to so construct and assemble the links forming the bed spring that the main body portion of each link shall lie in and form the upper surface of said bedspring and present to the mattress which is placed thereon an even and smooth surface with all the parts which project from said surface projecting downwardly therebelow, so that the mattress may be pulled across the upper surface of the spring with case without tearing or wearing said mattress. r

The invention consists in the combination and arrangement of parts set forth in the following specification and patricularly pointed out in the claims thereof.

Referring to the drawingszFigure' 1 is a plan view of a portion of my improved bed spring. Fig. 2 is an end elevation of the same. Fig. 3 is a side elevation of the same.

Like numerals refer :to like parts throughout the several views ofthe drawings.

In the drawings, 5, 5 are links forming a portion of a series of links extending longitudinally of the spring. 6, 6 arelinks forming a portion of a series extendinglaterally of the spring. All of the links are formed of wire and the entire spring is formed of. a plurality of series of links 5 joined together and extending longitudinally ofthe spring and a plurality of series of links o1ned together and to said longitudinal series and extending laterally of thespring.

The links 6 each consists ofa body portion 7 and two end portions 8,8-terminating at 9, 9. The end portions 8 are each bent downwardly to form an eye 10 and the terend of the link 6. The eyes 10, 10 lie in a vertical plane.

The link5 is formed of wire and consists of a body portion 11, the opposite ends of said link terminating in eyes12 and 13. The eye 12 is formed by bending the end portion 14 of the wire downwardly, with its termination 15 welded to the under side of the body portion 11, thus forming an eye which lies in a vertical plane. The other eye 13 is formed by bending the end portion 16 of the wire forming the link downwardly and laterally to form a horizontal eye, the termination 17 of the end 16 being preferably welded to the under side of the body portion 11. It will benoted by reference to Fig. 3 that the top or upper surface of the together and the links 6, Gare joined to the horizontal eyes 13 of the links 5, 5. It will thus'be seen that the links 5, 5 are joined directly together, while the links 6, 6 are joined together to forma series by means of the horizontal eyes 13of the links 5. 7

It will be noted that the body portions 11,

11 and 7 7 of the links 5 and 6, respectively, liesubstantially in the same plane, so that said body portions constitute the upper surface of the bed spring,and that all the terminating ends of the wireswhich form the links, both 5, 5 and6, 6,'project below the body portions, so that said'spring presents only the rounded wire bodyportion as an upper surface thereof and a mattress when placedthereon or when dragged thereover will not be worn or torn thereby.

The spring, as a whole, can be assembled and welded upon an electric welding machinewhich is to form the subject matter of a separate application for Letters Patent by applicant.

While Iprefer to weld the terminating ends of the links to the body portions therenating ends of the wire's'to the. body portions thereof. The welding of the ends of thelinks to the body portion thereof to formlthe links, in addition .to making a En STATES PATENT orrrcn. I

before described without welding the termismooth and light construction, prevents the eye from opening under tension caused by the weightupon the spring and, therefore,

' prevents the spring from sagging after having been used for a time. This construction, therefore, adds to the durability and resiliency ofthespring as a whole.

It will beseen that by welding the terminations of the end portions ofthe difierent links to the body portions thereof, great strength is'given to the eye portion of the link as compared with a link in which the eyes are made by simply bending the same but in which the termination of the end of the wire is not soldered to the body portion,

so that links made in accordance with my dinal -members comprising a plurality of successivelinks, connected directly to each other, each of said successive links consisting of a piece of wire, each of the end portions ofsaidwire being bent to form an eye, each of said end portions at its termination being welded to the body portion of said wire, whereby said eyes are completely closed, and a plurality of lateral links connecting links of adjacent longitudinal membersltogether, two of said lateral links connected to one eye of one of said longitudinal rections and connected at their opposite ends c as links extending therefromin opposite dito one eye of one of each of the laterally ad- I jacent longitudinal links.

2. In a. bed spring fabric, a plurality of longitudinal members, each of said longitudinal members comprising a plurality of successive links, each. of said successive links consisting of a piece of wire having a straight body portion in alinement with the body portions of the others of said successive links, each of said end portions being bent to form an eye, said eyes being interlocked with the eyes of the links adjacent thereto, and a-plurality of lateral links connecting the adjacent longitudinal members together, each of said lateral links terminating at its opposite ends, respectively, in an eye, said eyes interlocked with the eyes of two laterally adjacent longitudinal links.

7 3. In a bed springfabric, a plurality of longitudinal members, each of said longitudinal members comprising a plurality of successive links connected directly to each other, said successive links being duplicates I of each other, each-ofsaid links consisting of a piece of wire having a straight body portion in alinement with the body portions of the others of said successive links, eachof the end portions of said wire being bent to forman eye, and a plurality of lateral links connecting adjacent longitudinal members together, each of said lateral links termiother, each of. said successive links consist- A ing of a piece of wire, one end of which is bentto form a horizontal eye and the other end'of which is'bent to form a vertical eye, the vertical and horizontal eyes of each of said links being interlocked with the horizontal and vertical eyes, respectively,of the links in said longitudinal member adjacent thereto, and a plurality of lateral links connecting adjacent longitudinal members together, each of said lateral links terminating at its opposite ends, respectively, in an eye, said eyes interlocked with eyes of two laterally adjacent longitudinal links.

I 5. In a bed spring fabric, a plurality of longitudinal members, each of said longitudinal members" comprising a plurality of successive links connected directly to each other, said successive'links being duplicates of each other, each of said links consisting of a piece of wire having a straight body portion in alinement with the body portions of the others of said successive links, the opposite ends of each of said wires being bent to form vertical and horizontal eyes, respectively, and a plurality-of lateral links connecting adjacent longitudinal members together, each of said lateral links terminating at its opposite ends, respectively, in an eye, said eyes interlocked with eyes of two laterally adjacent longitudinal links.

6.
